Title: Diesel engine inlet air temp. control - uses fuel injector position to control valve recycling fluid from cooler
Inventor: BRISSON ROGER
IPC: F02B29/04
Filed: 1975-03-24
Abstract: Cooling water from a tank is pumped through the non-return valve to the engine. When starting at low temperature a further valve is opened to allow the water to flow through the heater before reaching the engine. The water then flows through the thermostatic valve which controls the volume flowing to a final cooler and how much flows to the primary cooler via the valve to the final cooler. One valve is controlled by the position of the fuel injector which in turn is controlled by the speed control.

Title: Wind driven generating system - uses inflatable bags around rotors to increase wind speed over blades
IPC: F03D1/04
Filed: 1975-04-17
Abstract: The rotor is mounted in a tubular housing and drives a generator. The housing is surrounded by a number of inflatable bags. Whne these bags are inflated they deflect the streams of air from the surrounding zone into the housing and over the rotor blades. A generating system is built up from a wall of inflatable bags with equally spaced holes for the rotors. This arrangement increases the velocity of air over the blades of each rotor with a corresponding increase in power from the generator. The power output can be controlled under varying wind conditions by varying the degree of inflation of the bags.
